What is the GraphQL Data API, and what are the Modelling Implications of It?

Thomas Frisendal

GraphQL is getting a lot of interest. GraphQL is a Facebook Open Source project, which started out in 2012. It is a data API, based on the graph data model. In Facebook’s own terms: “… GraphQL, a query language created by Facebook in 2012 for describing the capabilities and requirements of data models for client‐server applications”. Clearly this means that there are data modelling activities in and around a GraphQL project and its’ schema(s).

This presentation first gives you an overview of GraphQL from the data model perspective. Then you will get insights into how to do quality GraphQL data designs, how to avoid structural mistakes (when orchestrating data from multiple sources), and visualize them by drawing highly communicative property graph diagrams of your data APIs.
